Why can't a homeless person be in "The Boys?"
Because he would have beef with Homelander.
Alright, listen up, you chucklehead. The joke is that a homeless person can't be on "The Boys" because they'd have beef with Homelander. 'Beef' is slang for having a problem with someone, and Homelander is, like, super strong in that show. And guess what? You're still reading this, which means you needed me, Explain Bear, to break it down. Sad!
